the position to Wind the thread upon the peint of the bobbin7 'the said cam it gives to the rollers their minimum speed. Between these two extreme points the variations are corresponding and proportional., because the toothed cam E has the same profile as the cam Q and the conjugated inovemen.Jr

As the special form of the toothed cam 'it tends to change every instant the distance between the axes of the cam E and pinion l? pio vision must bemade `for permittino' this ya riation to be produced While mail t ning the toothed cam E and the pinion P in proper gear. This result is obtained in the ioll'owin g manner: It has been stated that the toothed cam E is keyed upon the shaft N. Its center et' rotationv is then invariable. 0n the contrary, the ,axle of the pinion P is supported in a triangular or sector-like frame O l i3, 'oscillating at 0 about the shaft V V `and carrying along its branch O l? the intermediate pinions 1.23 4, which transmit the movement of the pinion P to the pinion; P and consequently to the pinion P"and gears P" and D. The variable speeds imparted to `the pinion P by the toothed cam E are then transmitted 'to the large gear D of the differential movement and consequently to the roller C. The pinion P, instead oi being driven by in termediate gears 1 2 3 4,' may be driven bythe intermediate shaft and bevel-gears or byan endless chain in the arrangement which l preferably em ploy the oscillating movement of the movable frame or sector O P B is produced not solely by the toothed cam E, but at the same time by a second antagonistic cam S, keyed also upon the shaft N and operating upon a relier Il, securcdfupon the other branch O B oil the sector and calculated to maintain exactly in 'gear the teeth oi Jthe cam E and the pinion P. In this manner the engagement is always sure, the strain on the shaft 'N is equilibrated, and the movement of the sector is smoother and more certain than if a spring or a counterpoise were employed instead of the roller and combined with that which is generally em-l ployed to lay the thread .at the bottom of the bobbins at the commencement rof the building; bnt l prefer to make the bobbin with a conical face corresponding with the cone of the winding. y What I claim my invention s- The combination with the toothed cam E .and the differential movement .for transmitting motion to the drawing rollers, of a train ot gearing between said toothed cam E 'and said diferentia'l'mmem ent, 'a .movable sector ci. rrying said :train 'and la cam S of a .form corresponding with the cam E crcontrolling the move-ment of the said sector, substantiallyfas herein described.
